Re: [PATCH net-next + leds v2 3/7] net: phy: add simple incrementing phyindex member to phy_device struct

names are not suited for this, since in some situations a PHY device
name can look like this
  d0032004.mdio-mii:01
or even like this
  /soc/internal-regs@d0000000/mdio@32004/switch0@10/mdio:08
Clearly this cannot be used as the `device` part of a LED name.
